Summary: SARS-CoV-2 can survive in common beverages, with minimal reductions in some types such as milk and beer, while others like cocoa, coffee, tea, fruit juices, and wine contain antiviral compounds that can inactivate the virus. Hard liquors containing 40% alcohol can immediately inactivate SARS-CoV-2, but mixing them with non-alcoholic beverages reduces the antiviral effects. This study suggests that beverages contaminated with SARS-CoV-2 could potentially be a vehicle for virus transmission.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
